UK-based Ceramic Fuel Cells has sold its first BlueGen domestic-scale, fuel cell-based CHP units in Europe, to German utility EWE, which has ordered three units, for delivery in Q2 and Q3 this year. The company has previously announced the proposed installation of similar units into Japan and Australia.

EWE will install and operate the units in EWE facilities and family homes in the north west of Germany.

About the size of a dishwasher, each BlueGen unit can produce twice the electricity needed to power an average home, says the company, with the surplus electricity being sold back to the grid. BlueGen also produces heat, to make enough hot water for an average home.

Ceramic Fuel Cells says it has achieved the highest electrical efficiency of any product in the market for small-scale power and heat products. The company has been working with EWE since 2005.
